New files for doing a selection model. Not finished yet and thus not in

Browse Source 
2000-07-25  Christopher James Lahey  <clahey@helixcode.com>

	* e-table-selection-model.c, e-table-selection-model.h: New files
	for doing a selection model.  Not finished yet and thus not in
	Makefile.am.

	* e-table.c, e-table.h: Renamed the new dnd signals so that they
	won't conflict with the widget signals.
